After the collapse of plans for a common 2010 car launch event, the newly rebranded Mercedes GP team looks set to reveal its new single seater in Stuttgart late in January.

The German Sunday newspaper Bild am Sonntag said the event will probably take place at the Mercedes-Benz museum in Unterturkheim.

Both Michael Schumacher and his countryman and teammate Nico Rosberg will be present.

Bild am Sonntag also said Schumacher, to turn 41 this coming Sunday, is not scheduled to test the car until 10 February at Jerez.

The first group test of the winter pre-season period will take place more than one week earlier than that at Valencia.
